CORROSION BEHAVIOR OF ZINC COATED STEEL REBAR IN HIGH-STRENGTH REINFORCED CONCRETE
A large number of reinforced concrete structures subjected to chloride ions. Two basicapproaches for preventing corrosion of reinforcing steel embedded in concrete are: Increasing theconsolidation of concrete and using different coating on rebars. In present research steel rebarsare coated in different ways: a) 40 µm of zinc electroplated on steel rebar b) Zinc powder withepoxy paste (zinc rich...
متن کامل09207 - Corrosion of Epoxy- and Polymer/zinc- Coated Rebar in Simulated Concrete Pore Solution
This work is a preliminary examination of mechanistic issues on the comparative corrosion performance of regular epoxy-coated rebar (ECR) and dual polymer-zinc coated reinforcement (DCR) in simulated concrete pore solution with and without chloride ions, at polarizations from +100 mV to -1000 mV in the saturated calomel electrode (SCE) scale and exposure periods of 1 month or longer. Both mater...
متن کامل08311 - Corrosion of Epoxy Coated Rebar in Cracked Marine Substructure Concrete
Epoxy coated reinforcement (ECR) has been used in Florida from the 1970s to 1990s but has been discontinued due to the observation of severe corrosion in some ECR bridges after short service times. Corrosion projections have been made in earlier investigations based on corrosion initiation and propagation concepts but did not consider the presence of structural cracks. The current research in p...
متن کاملCorrosion Performance of Epoxy-coated Rebar in Florida Keys Bridges
Severe corrosion of epoxy coated rebar in the substructure of 5 major marine bridges in the Florida Keys was detected after only a few years of construction. Corrosion occurred underneath the coating and was preceded by loss of adherence between the steel and the coating. Damage surveys of the bridges, which were built around 1980, were conducted from 1986 to 2000. Corrosion resulted in delamin...
متن کاملEvolution of anodic stress corrosion cracking in a coated material
In the present paper, we investigate the influence of corrosion driving forces and interfacial toughness for a coated material subjected to mechanical loading. If the protective coating is cracked, the substrate material may become exposed to a corrosive media. For a stress corrosion sensitive substrate material, this may lead to detrimental crack growth. A crack is assumed to grow by anodic di...
